Kent Beck is the creator of Extreme Programming (XP) and a pioneer of Test-Driven Development, pair programming, and the Agile Manifesto. A programmer with 52+ years of experience, he co-created JUnit with Erich Gamma, co-invented CRC cards and design patterns in software with Ward Cunningham, and spent seven years coaching at Facebook. Today he runs the 'Software Design: Tidy First?' Substack newsletter (123,500+ subscribers in 195 countries), hosts the Still Burning podcast, and explores augmented human-AI coding. In April 2026 he publicly announced a Parkinson's disease diagnosis, continuing his mission to help technologists feel safe in the world.
Amos Wenger, known online as 'fasterthanlime', is a Swiss software engineer, open-source author, and technical educator based in Lyon, France. Through their blog, newsletter, videos, and the Self-Directed Research Podcast (co-hosted with James Munns), Amos has become one of the most beloved voices in the Rust programming community - known for long-form, deeply exploratory articles that make the inner workings of computers approachable and fascinating. Founder of the open-source organization bearcove, Amos builds real tools like fluke (HTTP/2 over io_uring), facet (Rust reflection), and rc-zip while funding this work through sponsorships and content creation.
Jon Gjengset is a principal engineer at Helsing, Rust systems programming educator, and author of 'Rust for Rustaceans' (No Starch Press). He holds a PhD from MIT CSAIL where he built Noria, a streaming dataflow database system offering up to 20x performance improvements. A prolific live-coder and YouTube educator since 2018, Jon co-founded ReadySet (a $29M-funded database startup), contributed to the Rust ecosystem, and teaches at MIT's Missing Semester.

Kris Nóva (1987-2023) was a principal engineer at GitHub, co-founder of The Nivenly Foundation, author, alpinist, and transgender activist who shaped the cloud-native infrastructure world. Best known for creating kubicorn, the Aurae runtime, and co-authoring Cloud Native Infrastructure with O'Reilly, she lived a life of radical generosity - growing Hachyderm from 700 to 40,000 users, founding the Privilege Escalation Foundation to support gender minorities in STEM, and writing Hacking Capitalism to help marginalized technologists navigate an industry that had once left her unhoused. She died on August 16, 2023, in a climbing accident in Seattle.
Predrag Gruevski is an independent software engineer, open-source creator, and Rust ecosystem luminary best known for building Trustfall - a universal query engine that lets you query anything from APIs to LLMs - and cargo-semver-checks, a semantic versioning linter that's becoming a cornerstone of the Rust publish workflow. A former MIT competitive mathematician turned principal engineer at Kensho Technologies, Predrag brings Olympic-level rigor to API design and compiler technology, writing and speaking extensively on correctness-first software development.
Sylvain Kerkour is a French software engineer, security researcher, and author best known for 'Black Hat Rust' - a hands-on book applying offensive security techniques with the Rust programming language. Self-described as a 'professional troublemaker', he writes about programming, hacking, and entrepreneurship at kerkour.com under the tagline '(Ab)using technology for fun & profit'. He is a vocal advocate for supply chain security in the Rust ecosystem and creator of the Bloom open-technology platform and the ChaCha20-BLAKE3 AEAD cipher implementation.
Xe Iaso is a technical educator, open source founder, conference speaker, Twitch streamer, and VTuber based in Ottawa, Canada. The CEO of Techaro and creator of Anubis - the open-source anti-AI-scraper tool now protecting GNOME, FFmpeg, Linux kernel archives, and UNESCO - Xe built a cult following of 400+ blog posts that mix deep systems engineering with irreverent philosophy. Known for pioneering developer relations teams at Tailscale and Fly.io, and for coining their own title 'Archmage of Infrastructure,' Xe is the rare technologist who turned shitposting into a career strategy and made it work.
